NetFlow Security

NetFlow Security Analysis is a cutting-edge sub-product of OneFirewall Alliance, built to provide real-time network metadata analysis. It offers visibility into allowed and blocked traffic at your organization’s perimeter — giving you a proactive edge in identifying potentially malicious activity that bypassed traditional security controls.

OneFirewall leverages proprietary threat intelligence from its Cybersecurity Alliance to detect previously allowed traffic that has since been identified as malicious.
